NAILING-S'IRII?.

Specification of Iietters Patent.

Patented Aug. 16, 1910..

Application filed September 13, 1909. Serial No. 517,433.

To all whom lt may concern:

Be it known that I, JOHN F. LESLIE, citivzenof the United States, residingat Madison, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Nailing-Strips, of which the following is a specication.

This invention relates to nailing strips for roofs and sides of buildings.

(lne object of the invention is to provide means for fastening felt, paper, or other flexible material to the sheathing on roofs and sides of buildings.

Another object of the invention resides in the provision of means whereby the felt, paper or other iexible material placed on the sheathin of roofs and sides of buildings may be lirm y secured against displacement and the overlapping joints of the felt, paper or other flexible `material bound tightly to effect both a water and Wind tight joint at the overlapping edges of said material.

A still further object is to provide a nailing strip of peculiar shape adapted to have a double gripping action upon the felt, paper or other Hexible material, which it is the purpose of my invent-ion to secure to the roofs and sides of buildings.

With the above and other objects in view, the present invention consists in the combination and arrangements of parts hereinafter more fully described, illustrated in the accompanying drawings and particularly pointed out 1n the appended claims, it being understood that changes may be made in the form, pro ortion, size andminor details without eparting from the spiritor sacricing any of the advantages of the invention.

lln the drawings Fi ure 1 is a plan View 1 of a portion of one o my nailing strips.

Fig. 2 is an edge view partly in sectionf` a circular concavo-convex formation, as shown particularly in Fig. 2, the body portion 5 of the strip being V-shaped or otherwise concave-convex 1n cross section, as shown particularly in Fig. 4, the concaveconvexv formation of the body portions 5 leading into the circular concave-convex formations of the enlargements 6, so that the strip is of concavo-convex formation throughout its entire length.

The characters 8 and 9 indicate felt, paper or other flexible material adapted to be placed over the sheathing on roofs and sides of buildings, and, as shown, these roofing sheets generally overlap, as shown in Fig. 4. It is along `the overlapping edges of these sheets 8 and 9 that my improved nailing strips are disposed, each enlargement 6 having a perforation 10 in it to permit of the passage therethrough of a nail or other fastening ll adapted to secure the nailing strips j upon they roof sheathing.

As shown in Fig. 4:, the opposite edges of the strips by virtue of the concave-convex formation thereof, become embedded slightly in the corresponding rooting sheets 8 and 9, and effect a water and wind tight joint, regardless of which direction the water may be carried by force of the wind. Moreover, the strip being narrow and concaved its entire length, as stated, it has much greater strength than one made flat or such as are made lof wire. By slightly tapping the strip with a hammer or other tool along the.

ridge thereof, as same is being nailed or tacked in position, same will have a tendency to flatten out and thus cause all the edgesof the enlargements as Well `as the longitudinal edges of the connecting strips to become slightly embedded in the sheet material to be secured. Moreover, the double gripping feature, induced as the result of the longitudinal edges vof the strips, relieve the fastenings 11 of more or less strain, because of the sharp edges of the strips being embedded in the roofing material, thereby rendering the strips not liable to any lateral play at all.. My improved strips may be equally serviceable in connection with boxes that are wrapped with paper, felt, and other material.

What is lclaimed is 1. A nailing strip composed of a metallic band or strip having a plurality of spaced perforated enlargements, the band or strip between the enlargements being V-shaped in cross section and its enlargements being band or strip having a plurality of spaced-10 eoncavo-convex in formation. l perforatedl concaVo-convex portions.

2. A nailing strip composed of a metallic In testimony whereof I aiiix my Signaband or strip having a plurality of spaced ture, in presence of two Witnesses.. 5 erforated enlargements, the band or strip etween said enlargements and the enlarge- JOHN F' LESLIE ments themselves being concaVo-convex in Witnesses: `omation.

3. A nailing strip composed of a metallic R. N. NELSON.
